Step-by-step explanation:65x2.8=182
Answer:
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
f(x) = 7x – 8x – 2
g(x) = 4x2 + 3x + 15
2. Which of the following answers shows the difference in the amounts of water released, h(x) = f(x) – g(x)?
h(x) = f(x) - g(x)
h(x) = 7x – 8x – 2 - (4x2 + 3x + 15)
h(x) = 7x – 8x – 2 - 4x2 - 3x - 15
h(x) = 7x – 11x – 17 - 4x2
<u>The correct answer is D. h(x) = 7x – 4x2 – 11x – 17</u>
Answer:
Actual mean: 223 pages
Predicted mean / estimate: 225 pages
Explanation below
Step-by-step explanation:
Mean = total amount ÷ # of numbers
155 + 214 + 312 + 198 + 200 + 170 + 250 + 260 + 215 + 256
Add
2,230
# of numbers = 10
2,230 ÷ 10 = 223
The exact mean is 223
If I were to predict the mean, I would say that a good estimation would be around 225, because I see that the highest number in the data set is 312, and the lowest is 155. If 312 is rounded down to 300, and 155 is rounded down to 150, the number exactly in the middle of 300 and 150 is 225.
Actual mean: 223 pages
Predicted mean: 225 pages
Hope this helps :)
The cost per child per child is $10 more at Mr Bob's buffet than it is at Sally's pizza safari.
